How to Root Samsung Galaxy SII GT-I9100

| On 13, May 2012

Alright, this post is part of the second leg of my tutorials for this week. This post will teach you how to root Samsung Galaxy SII on Android 2.3 Gingerbread. The steps are very simple and easy to follow provided that you read this a couple of times until you’re sure that you can do it. Otherwise, ask me anything you didn’t understand and don’t quickly jump into wrong decisions.

[important]

DISCLAIMER: NoypiGeeks will not be responsible for any damage   that may possibly occur to your device in any part of the process although it is unlikely to happen if you’ll follow the instructions carefully. Root at your own risk.

[/important]

Before we start, hold your phone and go to Settings>About Phone. List the letters indicating the kernel version because we will use it later.

Kernel version : 2.6.35.7-N7000XX

ABC-CL641703

Example:

Kernel version: 2.6.35.7-N7000XX

KJ4 -CL641703= remember KJ4

If you cannot find your match, get the one closest to it.

Example:

KG2 is close to KG1.

[important]Remember the letters representing ABC in your kernel. Disregard the other characters. It will be used to determine which CF-Root is needed by your device.[/important]

Also, if you don’t have Samsung Kies on your PC, you have to download the SG SII’s USB drivers HERE. Alright, let’s begin. Photo Credits: shivaranjan.com

1. Download Odin v1.85 HERE.

2. Download CF Root by Chainfire HERE. Since you already know your kernel version, choose it among the list.

  It can be something like this:

  SGN_XX_XEN_ ABC -v5.0-CWM4.zip

  Replace the ABC with the letters found in your own kernel.

3. Unzip the CF Root you downloaded to get a .tar file.

4. Launch Odin v1.85. NOTE: If you have Samsung Kies installed, make sure that         it is not running in the background.

5. The Auto-reboot and F. Reset time should remain marked. Leave the repartition unchecked.

6. Click the PDA button then choose CF-Root.tar.

7. Set your phone to USB Debugging mode. Go to Settings>Applications>Development>Check USB Debugging.

8. Next, turn off your phone and set it to download mode. To do so, press and hold the home, power, and volume button simultjneously until you see a download mode image in your screen.

9. Using a USB cable, connect it to your computer. You should see a “added!” message from Odin.samsung-galaxy-s-ii-odin2thumb2

10. Hit the start button and wait for your phone to reboot.

11. Finish!

You’ve just rooted your phone! Congratulations!
